The Rear Wing, on the other hand, is designed to generate a "down-force" at the back end of the vehicle, helping it to stay low to the ground. It is very effective for high speed cornering and general stability on the road, keeping the car "grounded". It is called a Wing because of its resemblance to an aircraft wing, although mounted in reverse.

There are different types of spoilers depending on their use, location in a vehicle, and the vehicle type. One common type of spoiler is the wing. Usually, wing spoilers are firmly mounted at the rear of a vehicle. The purpose of the wing spoiler is to create down force that provides the car an increased stability when accelerating at high speeds. Another type is the front spoiler, also called the air dam, which is located at the underside of the front bumper. Other spoiler types include tailgate spoilers, truck cap spoilers, and cab spoilers.

So what exactly is a Rear Wing Spoiler? According to the "experts", a Spoiler is NOT a Wing, and vice versa. Their missions in life are different. A rear spoiler is a device mounted on the rear deck of a car or truck ( or the rear roof of a van or SUV ) whose purpose is to "spoil" any air movement that doesn’t help keep the car on the road. They help with vehicle stability and fuel mileage. They are to be found on many high performance sports cars, as well as on some everyday passenger cars.
